To all whom t may concern.'

Be it known that I, THOMAS `OWEN BATES, asubject of the King of England,and residing at Liverpool, in the county of Lancaster, England, haveinvented Improvements in Machinery for Making I/Vafer` Biscuits, CupIVafers, and Similar Articles from Liquid (for which I have filedapplication in England July 2K1, 1920, Patent- No. 171,742), of whichthe following is a Specification. l y y This invention has referencetomachines for making wafer biscuits, `and similar articles, of theLkind wherein a `plurality of forming plates with moulds in them aremounted on a carrier in circular `or endless arrangement, andrevolved,and` they are lopened for the purpose ofv removing the cooked or madebiscuits or articles, and for introducing or charging the plates withthe fluid from which the biscuits or the like are made; and further ithas reference'to lmachines of this type in which the operation of theouter movable plates or covers are automatically effected by means ofcam or like devices. l

In the machines of this character, the pairs of plates are generallymounted on carrier cross bearers, which have wheels at their ends, whichrun on tracks on the main frames of the machine.

The top plate of each pair of plates is hinged at one side, sayto thecross bearers of the pairs of plates, and in opening and closing itmoves about the hinges, it being operated by cam tracks, and a roller onthe outer plate which being say carried on a projecting Outrigger onsame; the cam track being so arranged that at the time required,

the cam will lift the cover up and openv it, when the cooked articlesare removed from between the plates, and fresh liquid introduced;whereupon the cam closes the top plate again on to the stationary bottomplate mounted on the cross bearers.

The top plate is closed and kept closed on` the bottom plate during aportion required ofa revolution round the axis of the machine; and thisis effected by a shackle, link, or like device carried from the upperplate by a hinge, say on the projecting Outrigger bar aforesaid; andanother roller o-n it comes under a projection on a lower plate, and isheld there by another cam rack or way, with which lower roller on thesaidshackleor link operates.

This cam track or way is so formedthat` when a pair, of plates `is in acertain position, the roller on the shackle will come say onthe backside of a cam part, and

pull the shackleroller from under the pro,-` jection on the lower plate;and after this the aforesaid opening cam track comes into operation, thetop, plate then being free,

and the plate is opened.

In the drawings hereto annexed, the in-l vention, the nature of which isabove de-` scribed, is illustrated.` n In these drawings, Figure Figure3 a plan.

I 1 isa side ele-` vation, Figure 2 an end eleva-tion', and` Referringto the drawings, 1 is the top plate and` 2 the bottom..plate of eachpair 1v of plates,? plate 2 being carried by the` cross bearer orcarriage 3, which has` a pair of'running wheels 4 at eachside. The top plate is supported from thebearer or car` riage 3 byhinges 5, the hingeparts being bolted say to the back of the upper` l p l `so The Qutriggerpart 7 by which the topi` plate 1 1s opened and closed, is fixed to thei top of plate 1, and has at its Outer end a plate.

roller 8, which is acted upon bythe sta-r tionary cam` parts referred to;v and the device by means of which theplate 1 is kept closed on theplate 2, consists of a looped `shackle 9, hinged at 10 to the Outrigger7,V

and `having a roller l1 `within the loop or opening in it, whichoperates in connection with an inclined projecting locking part 12 onthe bottom plate 2: while beyond this below the horizontalcentral planeof the Inai chine to the top of the supporting bracket 16. and thencedown again where its exit end lies, 'in the normal path of the roller'8. The first part of this cam track, acting upon the roller'8, causesthe top plate 1 to be opened, until it is vertical, and then the cookedarticles are taken out of Ithe plates, and fresh batterV or fluid putin; and then by the further part of the track, as the plates travelalong, the top lplate 1 is moved back onto the lower one; and in thisaction the lower end of the shackle 9 will strike the upper incline ofthe nose of the projection 12, and force it outwards until the roller11r passes the extremity of it, which is when the plate- 1 is completelydown, and the'roller then moves under the bottom inclined or curved edgeof the projection 12, 'whentlie shackle roller 13 comes into con-l topplate, llto be pressed firmly on to the by the vcam 18, the rollerv 8 ofthe top plate,

bottom plate 2, and the plates to be closed.

These tracks or ways 17 extend along e'achs'ide of the frame; and at theend of the machine where the operation of the plates Lis to be effected,it ends at 17 X; and then at this point, the lower end of an inclinedreleasing'incline or cam.18 commences, andl comesinto action, whichoperates upon the `roller 13 in the opposite direction to the vrail yorway 17, and moves theroller 11 of the shackle 9 away from the lockingprojection 12 (the rail or way 17 being absent atthis part), and sofrees the top plate; and when the shackle is itself being operatedenters `the cam track 15,v and (the roller 11 of the shackle 9 being.clear of theprojection 12) opens the top plate in the manner described.

the platesall move together; and their travel inside face of'its rimforms a semifcircular lcontmuation of the way 17, both above and below.

rf'he main frames 23 carry the railway track 24ron which the carriagewheels 4L run; and the innerframes 20, on which the holding orlocking-rails 17 are fixed or formed, are carried from the back rails24;.

Vhat is Vclaimed is A wafer `biscuit and like article making machine,comprising a series of sets of plates adapted to travel along aApredetermined line, one of said plates being mounted for'. movementrelative to the other, opening' means fixed with relation to saidmovable plate, a cam way fixed with relation to the path of travel andadapted to cooperateuwith said opening means to raise said movable platewith respect to its cooperating plate, a locking projection carried byone of said plates and extending beyond the plane of' the plates, apivoted locking member movable with the plates and having a lockingroller `to engage beneath said projection to lock the plates together,said locking `member being providedvwith a setting roller arranged belowthe locking roller, and a guide carried by the machine to engage saidsetting roller at determinate points in the travel of the plates tooperate said locking member to cause its locking roller to engage anddisengage the locking projection.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
